Monoprice Speaker Wire, CL2 Rated, 2-Conductor, 18AWG, 500ft, White

Two conductors made of high purity (greater than 99.95 percent pure), oxygen-free bare copper. Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. Each conductor is jacketed with color-coded PVC for easy polarity identification. Entire cable assembly is jacketed in a black, CL2-rated PVC material.
